In general, the traditional dipole antenna is made by two coplanar
metal planes and a cable connected between the two metal planes, so
the area is larger than other components in the electronic device.
Also, when there are metal properties closed to the dipole antenna,
the operational efficiency of the dipole antenna will be obviously
decreased. However, in order to meet the demand of the people for
the electronic device with both of the variety functions and the

internal circuits in the electronic device is more and more
complex, and there're more and more electronic devices configured
with the metal housing. Hence, the configuration of the dipole
antenna is limited by said above properties, and the problem
thereof still needs to be improved.
As a result, it needs a dipole antenna with the function of metal
interference resistance presently in order to improve said above
problem.

DETAILED DESCRIPTION
In the following detailed description, for purposes of explanation,
numerous specific details are set forth in order to provide a
thorough understanding of the disclosed embodiments. It will be
apparent, however, that one or more embodiments may be practiced
without these specific details. In other instances, well-known
structures and devices are schematically shown in order to simplify
the drawings.
Please refer to FIG. 1, wherein FIG. 1 is the structure diagram of
the metal-interference-resisting dipole antenna 1 in an embodiment
based on this disclosure. As FIG. 1 shows, the dipole antenna 1
comprises a first metal plane 11, a second metal plane 12, a cable
13 and an antenna insulation layer 14. The first metal plane 11 and
the second metal plane 12 may be the plane and be parallel to each
other. Also, the first metal plane 11 and the second metal plane 12
are preferable to have identical shapes and sizes. On the other
hand, the first metal plane 11 and the second metal plane 12 is
able to keep being electrically insulated from each other through
the antenna insulation layer 14, and be electrically connected to
each other through the cable 13 connecting to an AC (alternating
current) signal source (not shown in FIG. 1). Hence, through the
antenna insulation layer 14, when the dipole antenna 1 is pressed
by an external force, the first metal plane 11 and the second metal
plane 12 won't be short circuit. Additionally, there's a distance d
between the first metal plane 11 and the second metal plane 12, and
the distance d is preferable to be between 4 mm to 5 mm in order to
keep the dipole antenna 1 operating in a proper efficiency;
however, this disclosure is not limited by it.
For descripting specifically about the first metal plane 11 and the
second metal plane 12, please refer to FIG. 1. As FIG. 1 shows, the
first metal plane 11 has a first upper surface 111 and a first
lower surface 112, wherein the first upper surface 111 faces away
from the first lower surface 112. Similar to the first metal plane
11, the second metal plane 12 has a second upper surface 121 and a
second lower surface 122, wherein the second upper surface 121
faces to the first lower surface 112 of the first metal plane 11,
and the second upper surface 121 is back to the second lower
surface 122. In this embodiment, since the first lower surface 112
of the first metal plane 11 faces to the second upper surface 121
of the second metal plane 12, aforementioned antenna insulation
layer 14 may be disposed on the first lower surface 112 and the
second upper surface 121. Hence, when there's an external force
forced on the dipole antenna 1, the first metal plane 11 and the
second metal plane 12 are not touched each other for avoiding being
short circuit. In addition, the antenna insulation layer 14 may be
disposed on the first lower surface 112 of the first metal plane 11
only; alternatively, the antenna insulation layer 14 may be
disposed on the second upper surface 121 of the second metal plane
12, and this disclosure is not limited by the configuration of the
antenna insulation layer 14.
For descripting specifically about the structure of the cable 13,
please refer to FIG. 2. FIG. 2 is the sectional view of the cable
13 of the metal-interference-resisting dipole antenna 1 in an
embodiment based on this disclosure. As FIG. 2 shows, the sectional
view of the cable 13 is formed by a plurality of concentric
circles. From the center to the periphery, the cable 13
sequentially includes an inner conductor 131, an insulator 132, an
outer conductor 133 and a protective layer 134. Specifically, the
inner conductor 131 and the outer conductor 133 are adapted for
transmitting the signal with two opposite transmission direction.
Also, the insulator 132 is able to make the inner conductor 131 and
the outer conductor 133 being electrically insulated from each
other, and the protective layer 134 is able to cover and protect
the outer conductor 133 so as to make the outer conductor 133 being
electrically insulated from other conductive properties.
Particularly, corresponding to the inner conductor 131, the outer
conductor 133 is disposed at the outer side of the insulator 132.
That is, the inner conductor 131 is partly covered by the insulator
132, and the outer conductor 133 may be disposed as the way of
covering the insulator 132; alternatively, the outer conductor 133
and the inner conductor 131 may be disposed as the way of two
separate wires, and be electrically insulated from each other by
the insulator 132. Additionally, the outer conductor 133 is partly
covered by the protective layer 134 in order to protect the
structure of the cable 13 and keep the conductivity of the cable
13.
For descripting specifically about the dipole antenna 1, please
refer to FIG. 1 and FIG. 2 together. Aforementioned inner conductor
131 comprises a first inner connecting end 131a and a second inner
connecting end 131b, wherein the inner conductor 131 of the cable
13 is partly exposed from the insulator 132 for forming the first
inner connecting end 131a, and the first inner connecting end 131a
is electrically connected to the first metal plane 11 in order to
form the feed point 110 at the connection. In addition, the inner
conductor 131 is covered by the insulator 132 between the first
metal plane 11 and the second metal plane 12. Therefore, it may
avoid the unexpected short circuit causing by the segments of the
inner conductor 131 except for the first inner connecting end 131
contacting with the first metal plane 11, and it may also avoid the
unexpected short circuit causing by the inner conductor 131 is
contacted with the second metal plane 12. On the other hand, the
second inner connecting end 131b of the inner conductor 131 is
electrically connected to a AC signal source (not shown in the
figures) so as to receive the first feed signal. Similarly, the
outer conductor 133 has a first outer connecting end 133a and a
second outer connecting end 133b, wherein the first outer
connecting end 133a is between the first metal plane 11 and the
second metal plane 12. Moreover, the insulator 132 protrudes from
the first outer connecting end 133a of the outer conductor 133, and
the insulator 132 extends to the first inner connecting end 131a of
the inner conductor 131. Specifically, the outer conductor 133 is
partly exposed from the protective layer 134 so as to from the
first outer connecting end 133a, and the outer conductor 133 is
electrically connected to aforementioned second upper surface 121
for forming another feed point 120 at the connection. Additionally,
the outer conductor 133 is electrically connected to the AC signal
source at the second outer connecting end 133b for receiving the
second feed signal from the AC signal source, wherein the first
feed signal and the second feed signal are the AC electric signals
with opposite phase.
Please refer to FIG. 3, wherein FIG. 3 is the structure diagram of
the metal-interference-resisting dipole antenna 1' in another
embodiment based on this disclosure. The main difference between
this embodiment and aforementioned embodiment is: the first inner
connecting end 131a of the inner conductor 131 of the cable 13
electrically connected to the first lower surface 112 of the first
metal plane 11, and a feed point 110 formed at the connection. In
this embodiment, since the first inner connecting end 131a and the
first outer connecting end 133a are both between the first metal
plane 11 and the second metal plane 12, the first upper surface 111
and the second lower surface 122 both are flat planes. It is worth
mentioning, the dipole antenna 1 as shown in FIG. 1, since the
second lower surface 122 of the second metal plane 12 is not
electrically connected to the cable 13 directly, the second lower
surface 122 of the dipole antenna 1 is a flat plane. Therefore,
comparison with the dipole antenna mentioned in the prior art, the
area of the dipole antenna 1 and the dipole antenna 1' disclosed in
this disclosure are reduced, and the dipole antenna 1 and the
dipole antenna 1' further comprise the metal-interference-resisting
function. On the other hand, since both of the dipole antenna 1 and
the dipole antenna 1' have the flat planes facing to the outer
side, the dipole antenna 1 and the dipole antenna 1' are able to be
disposed and fixed directly at the inner side of the housing or
other elements. As a result, the dipole antenna 1 and the dipole
antenna 1' may be more flexible for configuration.
Please refer to FIG. 4, wherein FIG. 4 is the structure diagram of
the metal-interference-resisting dipole antenna 2 in another
embodiment based on this disclosure. As the dipole antenna 2 shown
in FIG. 4, since the connection and the configuration between the
first metal plane 21, the second metal plane 22, the cable 13 and
the antenna insulation layer 24 are the same as the dipole antenna
1 shown in FIG. 1, and the position for forming the feed point 110
and feed point 120 are also the same as the dipole antenna 1 shown
in FIG. 1, the detailed description is not illustrated again.
Comparison this embodiment with the embodiment in FIG. 1, the main
difference is the first side circumference 213 having a first
recess portion 214 forming a first opening. In addition, the first
side circumference 213 is a part of the first metal plane 21, and
the first side circumference 213 is connected the first upper
surface 211 to the first lower surface 212. Similarly, the second
side circumference 223 has a second recess portion 224, and there's
a second opening formed by the second recess portion 224, wherein
the first opening and the second opening are faced to the same
direction. Specifically, as FIG. 4 shows, both of the first opening
and the second opening are faced to the positive y-axis direction.
In addition, the second recess portion 224 is a part of the second
metal plane 22, and the second recess portion 224 is connected the
second upper surface 221 to the second lower surface 222. Since the
dipole antenna 2 comprises the first recess portion 214 and the
second recess portion 224, without the interference in the
operation of the dipole antenna 2, other elements are able to be
disposed in the inner side of the first recess portion 214 and the
second recess portion 224 based on the applications in practice,
and the space inside the electronic device is able to be used
efficiently and flexibly.
As the detailed descriptions illustrated above, this disclosure
provides a metal-interference-resisting dipole antenna. The dipole
antenna in this disclosure is made by folding the typical dipole
antenna, so the occupied space of the dipole antenna disposed in
the electronic device may be reduced, and the operation of the
dipole antenna may not be effected obviously when there's an object
contained the metal materials closed to it. The dipole antenna in
this disclosure not only comprises the unexpected result, but also
improves the problem of the space configuration in the electronic
device or other devices.
The embodiments depicted above and the appended drawings are
exemplary and are not intended to be exhaustive or to limit the
scope of the present disclosure to the precise forms disclosed.
Many modifications and variations are possible in view of the above
teachings.
